The Senior Network Engineer is the technical owner for the design,
implementation, monitoring, and ongoing support of the company’s hybrid network
environment and leads the network function, including cloud network operations.
This role is responsible for secure, reliable connectivity across offices,
retail locations, warehouse facilities, AWS and Azure cloud environments, and
remote users, including Cisco and Meraki switching and wireless infrastructure
and Palo Alto firewalls and virtual private network (VPN) services. A key
objective of the role is modernizing cloud connectivity by removing the
company’s dependency on Cisco cloud services routers and replacing them with
cloud-native technologies for Azure-to-AWS and cloud-to-site communication.
Working independently and in partnership with Infrastructure, Security, DevOps,
application teams, business stakeholders, and vendors, the engineer establishes
standards, leads network projects, resolves complex incidents, and improves the
performance, resilience, security, and scalability of the network.
RESPONSIBILITIES
Serve as the network subject matter expert and technical owner for the
architecture, configuration, implementation, monitoring, maintenance, and
lifecycle management of the hybrid network environment.
Provide technical guidance and mentoring to other engineers.
Configure and support Cisco and Meraki switching, routing, wireless, and site
connectivity across offices, retail locations, and warehouse facilities.
Configure, administer, and continuously improve Palo Alto firewalls, security
policies, site-to-site VPNs, remote-access VPN services, and related network
security capabilities.
Own the design and execution of the cloud connectivity roadmap, removing
dependency on Cisco cloud services routers and implementing cloud-native
networking (such as AWS Transit Gateway, Azure Virtual WAN and VPN gateways,
and native private connectivity) for Azure-to-AWS and cloud-to-site
communication.
Partner with DevOps on cloud network standards, security controls, and
infrastructure-as-code for cloud networking.
Lead the design and deployment of networks for new facilities and the upgrade
of existing sites, including expansions and relocations, covering
requirements gathering, design, equipment selection, implementation, testing,
documentation, and transition to operations.
Monitor network availability, performance, capacity, configurations, logs,
and security events; establish actionable alerts, identify trends, and
resolve issues before they materially affect business operations.
Troubleshoot complex routing, switching, wireless, firewall, VPN, DNS, DHCP,
latency, packet-loss, and cloud-connectivity issues, coordinating with
carriers and vendors as required.
Keep network devices current on security patches, software, and firmware;
implement configuration management, backup, vulnerability remediation, and
change-control practices for physical and virtual network devices.
Partner with the information security team to implement defense-in-depth,
segmentation, least-privilege access, zero-trust principles, intrusion
prevention, and appropriate logging and threat-correlation controls.
Develop and maintain network architecture diagrams, configuration standards,
operating procedures, asset records, support documentation, and
disaster-recovery information.
Participate in incident response, problem management, root-cause analysis,
and corrective-action planning for network and security events.
Automate repeatable network administration, validation, reporting, and
monitoring activities using APIs and scripting where practical.
Manage technical relationships with telecommunications carriers, managed
service providers, and network technology vendors, including escalation and
service-performance reviews; partner with the Contracts team on circuit,
service, and renewal decisions.
Participate in an on-call rotation for critical network services.
